Title: A delay time control system for a data transmission system
IPC: H04L1/12
Filed: 1963-11-08
Abstract: 1,036,326. Data transmission. NIPPON ELECTRIC CO. Ltd. Nov. 8, 1963 [Nov. 13, 1962], No. 44169/63. Heading H4P. In a data transmission system in which mutilated received signals are corrected by repetition and in which the loop delay time may vary, an additional delay can be inserted in the loop should the transmitter timing pulses bear a certain time relation to the pulses timing the signals received over the return path. The invention is described for a known system in which signals are checked, character by character or bit by bit, by returning received signals to the transmitter. However, the invention is also applicable to systems wherein data is sent in error-detecting code, an error indicating signal being returned to the transmitter to initiate retransmission. At the transmitter the transmission circuit is controlled by clock pulses S occurring at the beginning of each transmitted frame (character or bit), and the receiving circuit by clock pulses R at the end of each received frame. If the times of occurrence of these pulses approach one another closely, it is uncertain whether repetition should start with a particular stored frame or the one adjacent it. To overcome this, the clock pulses R and S are expanded, as at R<SP>1</SP> and S<SP>1</SP>, and, if they overlap, as they do in the example shown, a ¢-frame delay is added into the return path so that R<SP>1</SP> is now well separated from S<SP>1</SP>. The delay may be added to the transmission path.

Title: Process for the liquefaction of starch
IPC: C12P19/14
Filed: 1965-10-21
Abstract: In a process for the liquefaction of starch, a water-soluble calcium compound is added to an aqueous slurry of starch-containing material so as to produce a calcium content molarity of 0.007-0.03, and the resulting slurry is subjected to the action of an amylase.  The slurry may also contain a water-soluble sodium compound so that the sodium content molarity is 0.014-0.06, the molar ratio of sodium/calcium being about 2/1. The enzyme treatment may be carried out at 170-200 DEG F. for 25-45 minutes at pH 5.5-7.7.  The starch-containing material may be a pure starch or e.g. starch liquors, ground whole corn, corn flour, brewers' grit or cereal milling plant fractions such as centrifuge streams, clarifier underflow and degermed primary mill slurries.  Specified calcium compounds are calcium acetate, chloride, citrate, hydroxide, hypophosphite and lactate, while the sodium compound may be sodium chloride, acetate, carbonate, bicarbonate, citrate and hydroxide. The liquefied starch may be converted to dextrose by action of an amyloglucosidase.ALSO:Dextrose is made by subjecting to the action of amyloglucosidase, a liquified starch (see Division C3) produced by treating an aqueous calcium-containing slurry of starchy material with amylase (calcium molarity 0.007 to 0.03). In examples, saccharified products having dextrose equivalent sugar contents of 96.5-97.6% are produced from corn starch.

Abstract: 1474966 Hall effect devices INTERNATIONAL BUSINESS MACHINES CORP 15 Oct 1974 [12 Nov 1973] 44717/74 Heading H1K A Hall effect chip 17 located within a cavity 18 in a non-magnetic (e.g. moulded plastics) housing 11/12 is mounted on a first magnetic member 16, there being a second magnetic member 21 extending into the cavity 18 towards but slightly spaced from the chip 17. The total gap between the magnetic members is thus only slightly wider than the thickness of the chip 17. The first magnetic member 16, or a further magnetic member 15 magnetically connected thereto, extends to the same external surface of the housing as the second magnetic member 21. In the embodiment shown the second magnetic member 21 is T-shaped with its upper surface flush with the outer surface of the top section 12 of the two-part housing. The first magnetic member comprises a carrier plate 16 mounted directly on the central section of a U-shaped member 15 the limbs of which terminate flush with the upper housing surface. The central section of member 15 is located in a groove 13 in the base housing section 11. The plate 16 may be omitted. The magnetic members 15, 16, 21, which are preferably of soft iron, function as flux concentrates for the Hall chip 17. A permanent magnet may be placed on the upper housing surface slideable between a first position where its respective left and right hand ends engage the left hand limb of member 15 and the member 21 and a second position where the same ends respectively engage the member 21 and the right hand limb of member 15. Since the Hall voltage polarity will be opposite in the two positions the arrangement operates as a switch. An extension of one of the limbs of member 15 so that it turns over and contacts member 21 provides a detector of current flowing in a conductor passing through the extension loop. In a modification of this arrangement the member 15 has no upright limbs, but an external U- shaped magnetic member (26) Fig. 6 (not shown) provides the necessary closed loop through which the current conductor passes.

Conveyer 11 comprises rollers 24 driven by a belt (28) threaded over the rollers 24 and over idler rollers (29), Fig. 2 (not shown). Some driven rollers 24a are extended to support articles of extra width. Hold-down roller assemblies 34, in addition to being adjustable longitudinally of tracks 33, are vertically adjustable and are biased downwardly by springs (42), Fig. 4 (not shown). This conveyer also has hold-down rollers 40a, 40b. The output conveyer 12, with hold-down rollers 53, 53a, has rollers 50 driven at variable speed and independently of the conveyers 10, 11. Section 13 of the output conveyer includes a wall 62 for fine alignment of the articles, the wall carrying resiliently mounted rollers 67 whose axes are at an angle with respect to axles 57, 58 of rollers 55, 56 which support three endless belts 59. The wall 62 may be adjusted laterally. Before operation, the hold-down rollers 21 are adjusted such that their spacing from the rollers 40a is " D," i.e. is substantially identical to the length of the articles A. In a similar way the distance " W " between roller assemblies 53A and 40B is made equal to the width of the articles. By these adjustments, an article is simultaneously released from the control of one conveyer and transferred to the control of the succeeding conveyer. To avoid overlapping of the articles, if the length of an article is twice its width, the speed of the article on the output conveyer 12 must be at least one half as great as that of the input conveyer 10. The conveyers may all be of the belt type or all roller conveyers.
